Abstract
A β-sialon phosphor represented by general formula: Si6−zAlzOzN8−z (0<z<4.2) has as a host crystal, a crystal structure identical to that of a β-sialon crystal phase and having a bulk density of 0.80 g/cm3 or more and 1.60 g/cm3 or less. Also, a light-emitting element includes the β-sialon phosphor and a semiconductor light-emitting element capable of exciting the β-sialon phosphor.
